Internet Growth: Raw Data

The following data is from Network Wizards.
The columns in the following chart are:

Hosts

This is the number of machine addresses on the net as reported by
the nameservers. Many of these addresses may not have a machine which
responds to them. See the "Replied to Ping" column.

Domains

These are domains such as "mit.edu" or "internic.net". Each
domain is usually associated with some organization, be it a
university, company or other group.

Replied to Ping

This is an estimated number of machines that are actually
connected to the net and responding. This estimate was made by
pinging 1% of the hosts and counting repsonses. 'Ping' is a tool to
determine if a machine is up.
